fuelpump for my 1994 f 53

[1skatingrin]

I think i might have fuel pump problems when i tried to start motorhome after two week stay at campground it took a few seconds to start than was running badly.afterpulling out of site hooked up toad with engine off.restarted still running poorly drove down to exit gate ,turned off engine to turn in slip.when i went to restart the engine it would not even try to start the starter just spun the engine no start.was getting spark at #1wire,changed fuel filter ,distribtor cap and rotor,sparkplugs everthing looked pretty good.still no start.I should say that i had all batteries disconected to clean terminals durning my 2 week stay,would this couse the computer have to relearn itself? makeing it run poorly for a while? I am getting some fuel out of schrader valve got half gallon fuel in 30 seconds.not a heavy flow.I tried starting fluid directly into intake it did findley start but running poorly would not much throttle acts like starving for fuel . If i need to change pump where would be best place to buy it.do i need a complete drop in one?

If you replace the fuel pump I would get the new turbin style pump and sender from Ford.
I will attach the TSB 97-23-9 below.

You might try a fuel filter first.
Disconnecting the battery will not cause it to run badly as it runs in open loop most of the time anyway.
I disconnect my engine battery every day on the road when I stop for the night. I also leave it disconnected while at home and charge it with it disconnected after two or more weeks of setting.

A good place to start would be to chack to see if you have any codes in stored Computer Memory (CM).
Also run a electrical test of all your engine sensors and solenoid with the KOEO self-test.
If you do not know how go to this link below:

Also put a fuel pressure gauge on it before saying the fuel pump is bad. Ground pin #6 of the self-test plug and turn on the key. You should get 40-45psi pressure on the gauge.

thank you Subford.Im trying to get hold of pressure gauge.Ifound theself test plug just like your picture shows,do you just unplug from the cover?i dont wart to break anything.I am able to get started using starting spray directly into manifold it runs rough but am able to get rpm up high and hold steady for 30 seconds than back to pretty good idle.Goosing gas up and down seems to work good turning off engine started normally without spraying for 4 times in a row .throught i was good to get back on road But next time i tried to start back to square oneI should mention that im having 6 volt battery low voltage probaby bad cell,gen wont turn over just clicks and jacks dont have much lift, this is most likely result of bad battery.My door battery disconect switches dont work properly but as long as they stay closed i thought i was ok.i nown i am reaching for straws thanks for any replies

Yes the self-test plug just unplugs from the holding cover.
Low house batteries may effect the running of the engine if your parallel relay comes in and the voltage to the pump is dropping.
You may have to disconnect the parallel relay to get it to run right.
If you need direct assistance over the phone just email me your phone number and I will call you.
My email address is at the bottom of my post.

thank you subford so much for your much needed help. my fuel pump 't rwas 40 lbs so pump wasn't my problem.I was able to read codes using check engine light just as you sugested. I had lots of trouble trying to read them however I brouht my old camcorder out of retirement and recorded the light and saying flash every time i saw one. this helped me when i played it back on my tv screen using pause when needed.I had two codes 116 and 118 both for engine coolent sensor.I replaced this sensor only $30 and this Ford is running great again.My waterpump is leaking badly from weephole. I always fill rad before driving only 13 miles between campgrounds .do you think i caused the sensor to fail ? thanks again

I really like that idea ! I too had trouble with the flashing and beeping of the code reader and repeated the test a couple times. subford is a wealth of information and has helped me with a couple of problems.
